LaTeX Dates in Australian Format

08Nov09

The macro \today presents dates in US format, which can be annoying when you want dates to be typeset in Australian or universal formats. Use the following macros to typeset dates in Australian format.

% Format date in the form 12 March 2007, for example.
\usepackage{datetime}
\newdateformat{auDateFormat}{%
  \twodigit{\THEDAY}~\monthname[\THEMONTH]~\THEYEAR
}
\auDateFormat

To get the universal format, simply re-arrange the day, month and year components to conform to yyyy-mm-dd.

done

Screencast: How To Create A New Ticket On Trac

12Oct09

The video should make it easier for people to learn how use trac, rather than learning just from reading a textual tutorial.
